Design, validate, and document Technology-Assisted Review (TAR) and Continuous Active Learning (CAL) protocols for litigation document review with full defensibility documentation.

Design, validate, and document Technology-Assisted Review (TAR) and Continuous Active Learning (CAL) protocols for litigation document review with full defensibility documentation. Use when designing a predictive coding workflow, selecting between TAR 1.0 and TAR 2.0/CAL, structuring seed set methodology, planning elusion testing and statistical validation, documenting proportionality under FRCP 26(b)(1), integrating privilege screens, building issue coding hierarchies, or preparing a defensibility report for production. Also use when reviewing an opposing party's TAR protocol for objections, responding to court questions about review methodology, or preparing a joint protocol stipulation. Produces a complete TAR Protocol Document with statistical confidence levels and court-ready defensibility report. US federal/state primary; UK/AU markers included.

This skill designs and documents TAR/CAL protocols for defensible litigation document review. It selects the appropriate technology approach for the document corpus, builds the seed set and training methodology, designs statistical validation including elusion testing, integrates privilege screen workflows, structures issue coding hierarchies, documents FRCP 26(b)(1) proportionality, and produces a complete defensibility report with confidence levels meeting court acceptance standards per Da Silva Moore (2012), Rio Tinto (2015), Livingston (2020), and Lawson (2020). **Covers:** - TAR 1.0 (predictive coding) vs. TAR 2.0 (Continuous Active Learning / CAL) selection - Seed set construction: size, SME selection, document sampling, richness assessment - Training round procedures: iteration design, stopping criteria, performance tracking - Statistical validation: control set design, elusion testing, precision/recall metrics - Quality control checkpoints: periodic sampling, reviewer consistency, corrective action - Privilege screen integration: pre-TAR/parallel/post-TAR workflows, FRE 502(d) orders - Issue coding hierarchy design: responsiveness vs. issue separation, multi-label strategy - FRCP 26(b)(1) proportionality documentation: 6-factor analysis, cost-benefit framework - Defensibility report production: statistical confidence levels, chain of custody, audit trail - Opposing-party protocol review: objection identification and response strategy - Joint stipulation drafting: vendor-neutral protocol language, dispute-resolution mechanism - Generative AI integration considerations: LLM review, privilege risks, validation updates - ...
